Inverkan av nederbörd, temperatur och frost på årsringens egenskaper hos boreal tall (Pinus sylvestris L.) :

The wide distribution range of our boreal pine (Pinus sylvestris L.) provides a great variation in growing conditions and climate/weather factors that influence the wood development of the trees. A great number of extensive studies have been conducted over the years in order to clarify growth trends of this and other species over more or less wide-ranging areas. In this thesis effects of weather factors were instead compared between different forest stands from the about same geographical location. The effects of precipitation, temperature and frost on the year ring characteristics of pine were studied in the research forest of Svartberget Vindeln, in northern Sweden. The stands differed in site index and silvicultural treatment; fertile ? high stem density, fertile ? low stem density, poor ? high stem density and poor ? low stem density.

Utredning av behovsstyrd ventilation : En jämförelse mellan CAV och VAV

Denna rapport är ett examensarbete på C-nivå som görs i sammarbete med teknikkonsulten Ramböll. Det vanligaste sättet att ventilera en byggnad idag är med så kallad CAV-ventilation (Constant Air Volume). Denna metod bygger på att ett luftflöde bestäms för rummet och upprätthålls med konstant flöde. En annan metod är så kallad VAV (Variable Air Volume) som bygger på att flödet varierar efter behovet. Anledningen till varför man väljer VAV istället för CAV är att med CAV finns det ofta en stor risk att man överventilerar ett rum eller byggnad, just på grund av att flödet är konstant. Problemet med VAV är att det är en högre investeringskostnad än för CAV så metoden lämpar sig bara där energibesparingen är så stor så den täcker mellanskillnaden i pris.

The Psychology Driving&Barriers to Skunk Work Project

The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.

Energieffektivisering och analysering av inomhusklimat genom simulering : IVT Värmepumpar, Tranås

Syftet med detta examensarbete har främst varit att förbättra inomhusklimatet i byggnaden Greenhouse, tillhörande företaget IVT Värmepumpar i Tranås. De anställda upplever problem med värme i byggnadens utbildningslokaler främst under sommarhalvåret. Tid har även lagts på att ta fram åtgärder som sänker byggnadens energianvändning i form av el och värme.Då examensarbetet utfördes under hösten användes ett simuleringsprogram för att få en bild av inomhusklimatet under sommarhalvåret. En modell av byggnaden byggdes upp i simulationsprogrammet, komplett med ventilations- och värmesystem.För att validera modellen som konstruerats utfördes flertalet mätningar under en veckas tid. Simuleringsmodellen kalibrerades sedan mot dessa mätningar för att efterlikna de verkliga förhållandena i så stor mån som möjligt.

Integrerade ledningssystem : Drivkrafter, möjligheter och hinder

The world is changing and the business context is no exception. One of the clearest tendencies is a tougher business climate with harder competition due to increased international trade and the expansion of the e-business. At the same time the customers are becoming more sophisticated and demanding. The last decades have also meant that tougher and more frequent demands are being aimed at the businesses from a wider variety of stakeholders; demands regarding how environmental issues, social responsibilities and business ethics should be dealt with. All of the above have driven companies towards implementation of different management systems to be able to cope with the demands as well as to ensure that these issues are being dealt with in an efficient and effective manner.

?Långt borta men nära?- en studie om socialsekreterares förväntningar på chefer och syn på arbete

The city of Gothenburg will within a few years recruit about 500 leaders. Depending on large pensions among leaders. It is important to have knowledge of the social workers expectations of leaders, their opinions of work and the leaders influence. It is also interesting to see if different generations have similarities or if they have different opinions.

Ekosystembaserad biomimik : hantering av klimatförändringar med hållbar design

Inom hållbar design har man under senare år börjat härma naturen för att hitta nya lösningar på människans problem. Naturens ekosystem fungerar som praktiska modeller för kretsloppsfungerande miljöer där energi och material tas om hand ? precis som visionen för den hållbara staden. Genom att dels förstå ekosystemets uppbyggnad, dels övergången från ekologi till design, kan man efterlikna ekosystem i den urbana miljön. Designstrategin biomimik är en tillämpning av detta förhållningssätt, där man efterliknar naturens processer i arkitektur.

Gruppdynamik i klassrummet : en studie om hur lärare arbetar med gruppdynamiken i klassrummet.

Vi har gjort en kvalitativ studie om hur lärare arbetar med gruppdynamiken i klassrummet. Vi utförde fyra intervjuer vilka utmynnade i fyra huvudområden: definition på gruppdynamik, synen på ledarskap, lärares strategier och kopplingen mellan inlärning och gruppdynamik. Informanternas bakgrund varierade från att enbart ha arbetat några år i yrket, till att ha 40 års erfarenhet. Vårt syfte med studien var att undersöka vilka strategier lärare använder när de arbetar med en grupp elever för att åstadkomma ett bra gruppklimat. Vi ville även synliggöra lärares tankar kring sitt ledarskap samt deras syn på kopplingen mellan inlärning och gruppdynamik.

Lärande för långsiktig hållbarhet: jämförande diskursanalys av medborgarskap för "hållbar utveckling" i Piteå respektive Växjö kommun

Sustainable development has become the ideology of the twentieth first century. As an important concept and as a framework of political action, sustainable development can at this point be considered as the very symbol of a paradigm in the international debate over environmental issues and the threats of climate change. But what does the concept of sustainability actually suggest? This thesis uses discourse analysis in order to examine the Swedish learning for sustainable development as to three different discourses on the national arena: the government and the municipals of Piteå and Växjö respectively. When the study foremost concerns official policy documents that contain associations with the study area, the methodology used takes into consideration both language, signs, metaphors and so called story lines.

Sustainable business practices : a review of eco-efficiency

The current demanding business environment requires corporations to act fast in finding effective solutions to problems given the myriad of challenges they face (Dyllick & Hockerts, 2001). The challenges include the impact of climate change on business practices, natural resource consumption, chemical pollution, technological change etc. Moreover, the forces of globalization, heightened concerns about the deteriorating quality of the physical environment and increased stakeholder power are also increasingly having a real influence on business practices (Rainey, 2008). Since 1992, the World Business Council for Sustainable Development (WBCSD) has encouraged the adoption of the concept of ecological efficiency (eco-efficiency) to support business efforts aimed at addressing some of these challenges. The aim of eco-efficiency is to reduce the amount of energy and materials used in production processes to achieve economic and environmental benefits (WBCSD, 2000).

Uppstart av Totalt Produktivt Underhåll på Tour & Andersson AB

In order to continue to be competitive in the current industrial climate, producers must increase efficiency at their plants. Several Swedish companies choose to utilise the principles of Lean production. Tour & Andersson AB (TA) has elected to create their own model using Toyota?s productions system which has been named TAPS (Tour & Andersson Production System). Following two years of working with TAPS the company has decided to introduce Total Productive Maintenance (TPM). Most of the work carried out in the maintenance department today is in form of repairs to already faulty equipment.

Dagvattnets föroreningar som potentiellt hot för en god ekologisk och kemisk status i ytvattnet : En kartläggning av Vallentuna tätorts dagvattenhantering utifrån dess tillsynsbehov

The EU's Water Framework Directive aims to a long-term and sustainable use of our water resources and wants to ensure good water quality in Europe's water bodies. Discharge of polluted stormwater into receiving waters can be a threat to their ecological and chemical status. Municipalities are responsible for supervision of the environmental quality standards (EQS) and therefore need to gain knowledge of current stormwater management, the expected level of pollution emissions and possible appropriate purification steps to ensure that the goal of good water quality is achieved.This master thesis aims to provide this knowledge in the example case of Vallentunas urban area and wants to prepare future oversight so that it can be assessed how much the discharge of polluted stormwater into the local receiving water is a threat to its status. With the help of maps, aerial photographs, site observations and individual discussions those areas are mapped where appearance of moderate to highly polluted stormwater could be suspected. The degree of pollution at the discharge points is determined based on land use upstream and uses standard values according to the administrators assistance "Tillsyn av dagvatten" (MSL 2014).The study identifies 100 areas in need of supervision regarding their stormwater management.

Styrdokument för kontorsbyggnation ur ett ekologiskt hållbarhetsperspektiv : Aspekter och argument

The construction and real estate industry represents a significant part of Sweden's total impact on the environment and mainly affects the following national environmental objectives: reduced climate impact, a good built environment and a non-toxic environment. By establishing internal rules, companies within the industry can reduce their environmental impact. SMT (AB Sandvik Materials Technology), a part of the industrial group Sandvik AB, has set a target that during 2014 develop a guiding document with special consider to the environmental impact during construction of office buildings, that they establish at the Swedish regional capital Sandviken, for both internal and external tenants. This study therefore aims to clarify which environmental aspects that the construction and real estate sector mainly are responsible for, and therefore should be part of a guiding document for a company for establishing office buildings, and to present arguments regarding the use of such a document. The study is based on literature studies and personal contact with other companies, in the form of e-mail conversations and a telephone interview.

Rabiata rabiesfeminister, orakade gaphalsar och andra aggressiva avarter : En studie av innehåll och argumentation i fyra feministiska bloggar

The purpose of this essay is to study how feminists portray themselves and their opinions about gender issues and other political matters in popular feminist blogs. The blogs that are studied are Lady Dahmer, Fanny Åström, Hanapee and Genusfolket. The overall essay questions are: How does the feminist bloggers present themselves? Which subjects are discussed in the feminist blogs? Which rhetorical devices does the feminist bloggers use? The theories that are used to answer the essay questions are the four spheres where there are inequality between the sexes, theories about third wave feminism, the rhetorical concepts ethos, logos and pathos and the SPADER-model for writing good argumentation. A descriptive method is used to study how the bloggers present themselves, a quantitative content analysis is used to count which subjects the bloggers write about and a qualitative rhetorical text analysis is used to study the rhetorical devices the bloggers use.The result shows that the two bloggers Lady Dahmer and Fanny Åström describe themselves with provocative words while the other blogs have more neutral descriptions.
